[Listen] Mike Starr's Last Voicemail -- I 'Need' Drugs

Alice In Chains bassist Mike Starr was on a desperate hunt for drugs the night before he passed away ... and TMZ has obtained the last voicemail Mike left for a person he was trying to score from hours before he died.

On the tape, Mike says he's willing to pay whatever it costs to get his hands on some "bud" ... and insists, "I need it so bad."

As we previously reported, Mike had been struggling with addiction for a while ... but just hours before he died, his roommate tells us the rocker was mixing methadone with anxiety medication.
